Security readout for executives and security teams
This issue can let attacker-controlled request metadata become stored script content inside FileRun Activity Logs. The business risk is mainly to administrators or staff who view those logs, because stored cross-site scripting can abuse their browser session. The source data names Afian FileRun 2021.03.26 only. Exposure appears limited to environments running Afian FileRun 2021.03.26 where Activity Logs render request metadata in the web interface. Risk is higher when untrusted clients can influence X-Forwarded-For and privileged users review those logs. Treat this as a moderate-priority web application issue unless FileRun 2021.03.26 is exposed in a sensitive environment. Prioritize inventory and vendor guidance first, because the supplied sources do not name a fixed release or active exploitation. Mitigation focus: Identify whether Afian FileRun 2021.03.26 is deployed.; Check FileRun and advisory sources for upgrade or patch guidance.; Restrict Activity Log access to users who require it..
